1. Background/Objectives and Goals
At 03:57 local time on 6 February, 2016, an earthquake of Richter magnitude 6.4 broke out, and it was measured
Intending to elucidate how this earthquake with epicenter in Kaohsiung city caused serious casualties in Tainan city, this study employs TELES, Taiwan Earthquake Loss Estimation System, to explore the latent mechanism     .
1.2. Objectives and Goals
1) To illustrate the significance of how to perform anti-earthquake practices and how to coordinate the support from different cities and counties by studying 0206 earthquake in Tainan.
Figure 1. The schematic diagram of Weiguan Jinlong building.
Table 1. Death toll in each building of Weiguan-Jinlong complex.
2) To polish the policy of disaster management to deal with the possible large-scale earthquake in Taiwan in the future.
3) To elucidate the reasons why Tainan city suffered the most serious disaster while the strongest magnitude occurred in Meinong Dist. in Kaohsiung city.
In this study, all the data are collected during the 0206 earthquake in
1) TELES application-the estimating model of trying to lives the estimating model I Number of people trapped in the wooden building * 0.226/4 = number of rescue teams required.
2) Number of people trapped in the non-wooden building * 0.226/4 = number of rescue teams required.
Total number of rescue teams required = (1) + (2).
(a) The estimating model II
The average possibility of rescuing 2 people by 1 rescue team in one day, within 4 days after the occurring of the earthquake.
Number of people trapped in the building * 0.226/2 = number of rescue teams required.
(b) The estimating model III
The average possibility of rescuing 1.5 people by 1 rescue team in one day, within 25 days after the occurring of the earthquake.
Number of people trapped in the building * 0.226/1.5 = number of rescue teams required.
In TELES system, PGA and PGV are used as the parameters in the modules, simulating the magnitude of the earth shake caused by the earthquake, to estimate the extent of damage on the structures of buildings   .
Figure 2 and Figure 3 reveal that, Meinonng Dist, where the epicenter located with the strongest magnitude of PGA, had not suffered damaged building. In contrast, Yongkang Dist, with middle-leveled PGA, has suffered the most seriously damaged buildings. After the thorough investigation and exploration, experts unanimously approve that the culprits of catastrophic collapse of buildings in Yongkang Dist are the bad design and faulty construction. Therefore, following suggestions and recommendations are made to enhance the rescue miss on when large-scaled disaster occurs.
In this rescue mission, the Tainan City Government rapidly set up forward command posts to effectively manage and control all the available domestic rescue force, gears, equipment, as well as related information, for the incident commander to use. Another key to the success of this rescue mission is the initiation of “Operation Demolition Shear, which enabled us to speed up digging and send rescuers into the building early on in order to save the trapped people as quickly as possible.

1) When rescuers are searching and cutting inside a building, it is advised to choose medium and small equipment, and send specialists to the disaster zone to assist rescuers if necessary.
Large handheld pneumatic or hydraulic equipment is either hard to manipulate or ineffective due to its relative large size and weight in a distorted and narrow space. Rescuers should detect signals of life in the preliminary phase of a rescue mission by cutting a small hole for life detectors to penetrate. Thus, medium or small electric equipment such as reciprocating saws, circular saws, or grinders will be more convenient. They are compact and handy, and will work even more effectively when a high quality cutting blade or grinding wheel is used. Once a trapped person is found, large equipment like an electric hammer will be used, and efficiency will be enhanced with the assistance of specialists (drillers) if conditions permit.
Also, we advise that a contact list of structural engineers should be created for rescuing assistance in a collapsed building like those in this case. The structural engineers engaged in this mission contributed a lot. They timely advised the rescuers on how to cut or break the buildings in an efficient and safe manner.
2) Signs of life should be cross-verified when using life detectors.
The noise in the scene hinders a life detector’s ability to detect weak signals from life. Even if the scene is ideally silent, signals from life may be discontinuous if the trapped person’s consciousness is unstable due to physical/psycho- logical trauma or hypoxia. Signals from the trapped people may become inaudible or indistinguishable when they are interfered by the noise at the scene. Unless the signals are regular, such as knocking three times in respond to a rescuer’s request, and with the readings of a life detector, signals from life may not be easy to identify. Some signals may be noises from other sources.
An example of that is the site F14. The readings from a sonar life detector were insufficient to determine if a survivor was trapped inside or not. A radar
life detector was then used to confirm. A through-wall radar life detector emits conical ultra-high frequency waves to rubble and then analyzes the signals bounced back to determine if inside trapped a survivor or not. The readings are more reliable. If a rescue dog is paired to cross-verify the signals, the accuracy will rise. For increasing rescue efficiency in a collapsed building, we suggest that more radar life detectors be purchased.
3) Radio channels should be properly allocated for support agencies and organizations.
The Fire Bureau has separated its radio channels for years. Available channels are Channel No. 2 for island-wide communication, and Channel No. 30, 31, 32, and 36 for
Below are our solutions. First, every support agency or organization designates a liaison officer to contact their sector commander in person. When a survivor is pulled out or if there is any request for support, the liaison will be sent to contact the sector commander in person under the leader’s command. Secondly, the Tainan City Government Fire Bureau provides the leader of every support agency or organization with a locally used radio and switches it to a specific channel. All the leaders will be able to contact their sector commander at any time. Thirdly, when support members are in action, the Tainan City Government Fire Bureau will designate one of its staffer to follow them, and the staffer will be in charge of contacting the sector commander.
4) A sector command post should be set up on every wing for rescue members to assemble and be under control, and meetings should be held on a regular basis.
To complete a large scale rescue mission, it takes more than just a commander to integrate information and assign tasks. Sector command posts have to be set up in order to assign tasks more specifically. The commander of every sector command post should keep a list of support members, assemble equipment, and assign operation area and time in order to integrate the rescue resources in the sector.
Besides, a spacious area has to be designated as a rendezvous for support members to rest and be under control. A rendezvous not only allows support members to have a better place to rest and dine, it also enables sector commanders to contact support agencies and organizations more easily, so the numbers of members in and out of the disaster zone will be clear. Plus, it serves as a convenient venue for regular meetings to be held. Efficiency will be achieved when leaders of all support agencies and organizations can discuss issues regarding current situations, needed support, teamwork approaches, task transfers and so on.
